.Application filed September le, MM2. Serial No. 588,211.

T 0 all whom t may concern Be it known that l', GEORGE GRBIN, a citizen of the United States, residing at uscaloosa7 in the county of Tuscaloosa and State of Alabama7 have invented certain new and useful Improvements in Cushioning Tires; and l do declare the followingF to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved cushioning` tire and one object of the invention is to provide a tire of the cushioning type which will be provided with a core formed of a plurality of sections which can be readily taken apart and put together and which will be enclosed in a casing` so that when put together, the various parts will be retained in the assembled state and prevented from moving out of the proper relstion with each other. l

Another object of the invention is to provide a cushioning tire having the core provided with a body portion having spring receiving` pockets therein and to provide e tread portion which will extend about they body portion and be formed of circumferentially extending sections havingl anchoring elements extending into the pockets and having operative engagement with the springs in the pockets to prevent movement of the tread portions circumferentially of the body portion. y Another object of the invention is to provide the tread portion of the core with facing means which will serve not only as a strengthening and reinforcingfacing4 for the core between the tread and body of the core but further serves as means to retain the tread forming sections in the proper relation to each other.

Another object of the invention is to provide a cushioning tire in which the outer casing whieh encloses the core will be provided with a bead portion havingl an improved arrangement of metallic band and rings which will serve to brace the tire and prevent side play which might tend to wrench the tire off of the wheel rim.

This invention is illustrated in the companying drawing, wherein:

Figure l is view showing the complete tire in section.

is improved tire is provided with e which has been formed in a plurality7 @tions which will be put together and an cuter Casin The body poros' d in this core has been formed in a plusections l which are formed of and will entend cireumferentially of end to end contact. Each of these i of the core has been provided with mtv of radially extending oassaoes Y j `pockets :2 in which springs 3 will be placed. These springs are coil springs and will serve to yieldably resist compression of the ocre when the tire is in use but will ol' course permit suiicient compression for the tire to tal-fe up jolts received in going roads. lfn the form illustrhtech V'1e core has been shown formed 'me but it will of course be iat any number of sections may es desired. The tread portion o' this fore is also formed in sections which entend fircinnerentially of the tire in end to end coiitacf'-` These tread forming` sections /i are of i suitable length so that they will overlap the end portions of the bodyforming' sections l and each at points intermediate the ends of the body-forming sections. Therefore, when the tread-form` ing` sections are anchored to the body-forming sections as will be hereinafter brought out` the tread-forming sections and bodyforming,- sections will be secured and prevented from having circumferential movement and further they will serve to retain lll l e the sections in their proper position. Each of the tread-forming sections 4- has been l vloed with inwardly orinpelements 5 which :ire in the form of hloclis to extend into the pockets i?. These erichoringg;` elements are of such size that the)v may lit into the springs 3. reinforcing and strengthening band is provided between the body of the core and inner face of the tread band. This reinforcingg` band is formed of metal plates 6 and 7 which extend circumferentially of the tire. The

extending arms or plates 6 are positioned in end to end con tact as clearly shown in Fig. a and these plates fit against the inner face ot the sections l which form the tread band. Each of the plates 6 iS provided With a cup eX- tension 8 Which is of sutcient size to receive the anchoring arm or block 5 as shown in Fig. 2. rlhe plates 7 fit against the plates 6 and are positioned in staggered relation to these plates so that they extend in overlapping relation to the end portions of the plates 6. Each plate l' has its end portions provided with notches 9 into which the cups 8 Will lit. By having the reinforcing bandv i'ornied of metal plates assembled as shown, the band may serve to reinforce the tread portion of the core but at the same time will have suilicient give to permit the tire to be compressed and take up jolts in going over rough roads. lBy having the anchoring elements extending into the pockets and Within the springs, the tread band is prevented :trom having transverse movement and therefore the Sections Which Jorm this tread band cannot move transversely oli ot the tread base ot the body. lt Will thus be seen that this tire may have the proper compression necessary but at the same time, it Will be so lormed that the sections which form the body, tread band and reinforcing band may not readily come apart. An inner ring or band 10 which forms a completing portion lor the core fits against the inner face of the core body and closes the inner ends of the pockets 2. This ring or band l0 has its core body engaging tace provided with grooves 11 which form ribs 12 so that When the tire is in use, this band or ring 10 may have a certain. amount o'li spread or bend transversely Without danger of cracking. Plates 13 which will be in the form of disks are provided in the inner ends of the poclrets 2 thus providing abutment plates for the inner ends of the Springs 3 and preventing the springs trom having a tendency to cut into the band 10.

Vllhen assembling the tire, the sections forming the body can be put in end to end contact about the ring 10 with the ring 'l0 and sections 1 positioned in a horizontal position upon a table or other suitable place ot assembling. The disks 13 will be put in the pockets and the springs then inserted and the plates t3 and T tien assembled as shoivn in Figs. 3 and et and put in place about the body with the cups 8 extending into the pockets and Within the coil springs. The sections torming the tread band will then be put in place with the anchoring arms or blocks 5 extending into the cups. lt will` et course. be understood that if desired the plates 6 can be iirst placed against the tread band 1forming sections with the blocks 5 extending into the cups and the plates T putin place and the assembled tread band sections and reinforcing band forming plates then put in place about the body of the core. Alter the core has been assembled, the casing 111 Will then be put in place about the core. This casing 14 is thickened as shown at 15 thus providing` the casing vvith a bead forming portion which will permit ot the tire being secured upon the rim ot' a Wheel. ln order to permit the rim portion of the Wheel to obtain a good grip upon the bead portion of the tire casing and hold the casing firmly in place and tightly about the core, there has been provided a. plurality o'i metal rings. Upon opposite sides oil the bead, there has been provided metal rings lo and against these rings lit a second set ot' rings 17. These rings 17 are provided with outwardly extending ilanges 18 which are curved transversely as clearly shown in Fig. 2 and extend to brace the tire upon opposite sides ot' the bead and prevent the tire from having transverse movement which would permit it to be readily Wrenched lose or torn when the tire is subjected to side strain. Other rings 19 fit against the rings 17 and are extended beyond the rings 17 to engage the side edges ot a band 20 which will tit upon the rim ot the Wheel. l/Vhen the tire is put in place and the rim tightened, the rim will engage the rings 19 and provide clamping means to securely hold the rings in place and hold the tire in place upon the Wheel. lt will thus be seen that this tire may be very easily assembled and lurther when desired, it can be readily talcen apart and lo() worn-out portions replaced.
